摘要： A wavelength selective optical switch of the present invention separates a WDM light emitted from an input port of an input and output optical system, according to wavelengths, by a diffraction grating, and thereafter, condenses the lights of respective wavelengths on MEMS mirrors respectively corresponding to the respective wavelengths, in a mirror array, to reflect them by a condenser optical system, to thereby switch optical paths for the respective lights. The condenser optical system is configured by combining a plurality of lenses whose focal distances are different from each other, and positions in an optical axis direction of the lenses are adjustable by a slide mechanism. Thus, despite an error in the focal distances of the condenser lenses, in a mounting angle of a spectral element or the like, a beam pitch at the condensing positions of the lights of respective wavelengths can be coincident with a mirror pitch in the mirror array.

摘要： Disclosed is a photonic switch that includes a plurality of optical-path switching means having movable light reflecting portions that guide light from each of a plurality of input ports to any output port among a plurality of output ports. Each of the optical-path switching means is made to produce a specific loss so as to reduce path-to-path variations in loss along the paths from the input to the output ports. Specifically, loss along a path is the total of loss based upon optical path length and loss produced by the optical-path switching means. A specific loss is produced by each of the optical-path switching means in such a manner that total loss is equalized from path to path.

摘要： An optical switch switches ports through which a beam is input and output and includes an optical system through which the beam passes; a movable reflector that is enclosed in a casing and reflects, at a variable angle, the beam that has passed through the optical system; and a transmissive window that is disposed in the casing at a position through which the beam passes, is made of a uniaxial crystal, and obtains a phase difference with respect to the beam passing therethrough having a wavelength λ. The phase difference is λ/4 times a positive odd integer and results from a setting of an orientation of a crystal axis and a thickness of the transmissive window.

摘要： A housing 20 is equipped for supporting, from a side, a platform of a wavelength selection device comprising an input/output port 10, a collimator 11, an expanding optical system 12, a spectroscopic element, a collecting optical system 14 and a micro electro mechanical system (MEMS) mirror array 15. Because the above noted optical member is supported from the side only, influences of a thermal expansion is limited to the height direction of the optical member and the optical axis direction. By these aspects, the influence of thermal expansion is limited to a two-dimensional from a common three-dimensional, thereby enabling a design of a countermeasure to an influence of a thermal expansion. Also, the support from the side does not create a dead space thereby making the wavelength selection device compact.
